Got a 2000 Yamaha blaster all stock besides fmf pipe, I start it and it start right up but when I go to start moving and hit the throttle it will rev up till about midrange rpm then stay there for a little bit then when it eventually hits high rpm it goes and revs fine, and it does the same thing when I go bellow high rpm, cleaned the carb put fresh gas in it and still does the same thing ordered new reeds they will be here Tuesday also when I’m in neutral it will rev fine just when in gear and moving
